Summer tire test of size 225/40 R18: one out of ten tires dies

A mere six points between first place and third in the 2013 summer tire test in the 225/40 R18 format. (For the current summer tire test by auto motor und sport with eleven tires of size 205/55 R 16) Then it even goes there in single steps. Given such a power density, tire tests in the high-performance sector seem like Sisyphean work. It is precisely the journey of discovery into the depths of the details, the elaborate derivation of the overall result, that make these tests so exciting.

Summer tire test with an 18-inch model in 225/40 format

At the top it is precisely the subtleties that are the icing on the cake and decide whether it is good or good. In motorsport, half a second per lap is now a world. In the current summer tire test with an 18-inch model 225/40, which was driven on a Mercedes A 250, between the fastest (Vredestein) and the supposedly slowest (Falken) in dry handling, ultimately more than two seconds per lap.

How, you don't go to the racetrack every day ...? Well, there are extremes in which nuances play a decisive role, for example when braking in emergency situations or when aquaplaning suddenly occurs. In everyday use, all ten summer tires used here work perfectly, but in the event of an emergency - and then there is always a borderline situation - every little advantage is decisive.

Best summer tire in the wet

Back to the summer tire test criterion of emergency braking in the wet, in which Vredestein, who is still so fast on a dry track, allows himself a distance of 47 meters to come to a standstill from 100 km / h. The falcon even needs a meter more. It leaves the well-sorted midfield at a respectable 42 to 43 meters. The Goodyear and the Pirelli stop a little better. And the Conti even brings the Mercedes A-Class to a standstill after an unbelievable 40.4 meters.
 
After that, the apparently perfectly harmonious combination turns onto the 1.7 kilometer wet handling track and, in addition to the convincing braking grip, also provides excellent traction. In addition, there are high cornering forces, precise steering and very balanced driving behavior. In the end it says: No one can compete with the Conti in the 225/40 R18 format when it is wet. It marks the best time and a total of 98 points.

Specialists don't stand a chance

However, it is precisely this specialty that fatally fatalizes the SportContact 5 in tire tests on dry roads. On this terrain, too, the summer tire is the type for one quick lap, offers a linear, direct steering feel and largely stays away from understeer. However, the more laps you put up with the 18-inch 225/40 models, the more extreme the ability then decreases - in the end almost to the point of giving up on your own.
 
The Vredestein bridles the horse the other way around: In dry conditions, the Ultrac Vorti is definitely sporty, reliable, durable. In the wet, on the other hand, the summer tire lacks precision and defined driving behavior. Even this relatively one-sided orientation was not enough for a top ranking at the end of the summer tire test. Only the hawk does worse because it does not reach the level when it is dry to at least eradicate its weaknesses when it is wet.
 
This is the case with the new Nokian Z Line in the 225/40 R18 format. The Finnish construction is not right at the forefront when it is wet, it is quick to handle, but not easy to move due to the load change reactions. The braking values ​​are also slightly below average. In dry conditions, however, the Z Line knows how to please a lot better. On the handling course, the summer tire is light-footed, agile, neutral and has a very good lap time. After ten laps at the limit, he stays relatively cool, similar to the temperatures in his Nordic country of origin.

The best summer tire has all-round talent

However, in order to get those points in the end that will make them one of the top three in the summer tire test in the 225/40 R18 format, more pronounced all-rounders are required. The Pirelli P Zero seems to be a candidate for it. With good, balanced performances, he came in fourth in the wet tests. In handling, the Italian excels with a high level of grip and precise steering behavior. However, the Mercedes A Class with the P Zero also tends to present load change reactions in a more jagged manner, and somewhat more demanding for the driver. Nevertheless, in the end, 83 out of 100 points remain on the credit side. In drought, however, only 130 are added. Nevertheless, the P Zero is recommended. Just like the Hankook Ventus S 1 Evo 2, which leaves a little bounce when braking when wet, but knows how to impress with its sportiness and precision on dry tracks.
 
We highly recommend the Goodyear Eagle F 1 Asymetric 2, which moves easily and nimbly despite its bulky name. In dry conditions, the Michelin Pilot Sport is even sharper, more direct and sporty, which ultimately means second place. First place at the end of all test series for tires in the 225/40 R18 format goes to the Dunlop SportMaxx RT. The summer tire achieves very good braking performance in dry conditions and finds the middle ground between sporty, balanced and safe driving behavior. And he is least impressed by ten fast laps in a row, which brings those crucial points. Because in the high-performance area, the air at the top is extremely thin - which was once again proven with great meticulousness.

Conclusion:
The Dunlop SportMaxx RT is not one of the absolutely fastest, but one of the most balanced tires in the test. It offers a relatively high steering precision in wet and dry conditions, and at no time does it attract any hectic reactions in the border area. Its gentle load changes nourish agility. The 225/40 R18 SportMaxx RT brakes excellently in dry conditions. And its big plus: Even after the tenth fast lap, the time and precision hardly drop.

This is how the 225/40 R18 summer tire test is assessed: The tire with the best value for each criterion receives the full number of points. When it comes to steering precision, what counts is directness and responsiveness from the central position, and when it comes to driving, the greatest possible neutrality at the limit.

Conclusion:
Above all, the high precision predestines the Michelin Pilot Sport 3 to take a detour to the racetrack. When it comes to lap times on dry slopes, the French rider is one of the best, offers a high level of grip and remains very stable even in fast corners. The delay performance is at the highest level. The steering feel is still excellent in wet conditions, but there is a little lack of grip at the top. The driving behavior remains free of pitfalls.

When it comes to steering precision, what counts is directness and responsiveness from the central position, and when it comes to driving, the greatest possible neutrality at the limit.

Conclusion:
With a great aquaplaning behavior, very good braking values ​​and an excellent lap time, the Goodyear is extremely strong in the wet. Even on a dry track, the Eagle F1 Asymetric 2 is at the forefront. It tends to appear a little softer in the steering and tends to understeer a little earlier at the limit. These properties increase with continuous load. In return, its braking performance is at the highest level.

This is how the 225/40 R18 summer tire test is assessed: The tire with the best value for each criterion receives the full number of points. In terms of steering precision, directness and responsiveness from the central position count, while in terms of driving behavior, the greatest possible neutrality in the limit area.

Conclusion:
The Continental SportContact 5 is a stunner in wet road conditions. In almost all test criteria, it marks the top, remains reliable in the limit area, top with a delay and offers an excellent level of grip. Even in dry conditions, the 225/40 R18 Conti is agile and fast - but not for long. Longer race track excursions end with significantly slower lap times and sometimes even with breakouts in the profile. The Conti summer tire is more suitable for everyday sporting use.

This is how the 225/40 R18 summer tire test is evaluated: The tire with the best value for each criterion receives the full number of points. In terms of steering precision, directness and responsiveness from the central position count, while in terms of driving behavior, the greatest possible neutrality in the limit area.

Conclusion:
On the dry test tracks, the Nokian Z Line came in second best in the summer tire test. The Finn is fast, reasonably precise in terms of steering feel, load changes come late and gently. The Nokian withstands the constant load well. When handling in the wet, the 18-inch model 225/40 is fast, with great grip on the front axle. Load change reactions come late, but then relatively jagged. The aquaplaning and wet braking behavior is not optimal.

In terms of steering precision, directness and responsiveness from the central position count, while in terms of driving behavior, the greatest possible neutrality in the limit area.

Conclusion:
With the new Ventus S1 Evo 2, Hankook is at the forefront in the test environment when it is dry. The Korean offers excellent steering precision and very agile driving behavior with very gentle approaches to understeer. Even in wet conditions, the driving behavior remains safe and yet sporty, because the very gentle load change reactions mean that the rear steers in a very predictable way. The Hankook loses touch with aquaplaning and braking. On the other hand, it can cope with the constant load.

This is how the 225/40 R18 summer tire test is evaluated: The tire with the best value for each criterion receives the full number of points. In terms of steering precision, directness and responsiveness from the central position count, while in terms of driving behavior, the greatest possible neutrality in the limit area.

Conclusion:
Although it has been on the market for some time, the Pirelli P Zero can still play a leading role in the test field in terms of wetness criteria. The grip level and the delay are very good. The steering behavior is also very precise, albeit paired with increased holding forces. When the load changes, the Mercedes A-Class with the P Zero reacts somewhat jaggedly, the aquaplaning behavior is moderate. When it is dry, the first turn-in is very precise, then the P Zero falls into understeer, which has a corresponding effect under continuous load.

This is how the 225/40 R18 summer tire test is evaluated: The tire with the best value for each criterion receives the full number of points. When it comes to steering precision, what counts is directness and responsiveness from the central position, and when it comes to driving, the greatest possible neutrality at the limit.

Conclusion:
The Bridgestone Potenza S 001 also has a few years under its belt in terms of its basic concept, and when it is dry it is on par with the Pirelli - including a lack of precision and desirable sharpness. In wet conditions, the Potenza S 001 initially provides sensitive steering, but then understeers to a relatively pronounced degree. The deceleration performance on an irrigated route could also be better.

This is how the 225/40 R18 summer tire test is assessed: The tire with the best value for each criterion receives the full number of points. In terms of steering precision, directness and responsiveness from the central position count, while in terms of driving behavior, the greatest possible neutrality in the limit area.

Conclusion:
Full score for dry handling! The new Vredestein Ultrac Vorti is actually the fastest tire in the test. After the first lap, however, the good precision decreases and the tendency to understeer increases. However, no trace of any signs of dissolution. On a wet road, however, there is nothing to be desired: the steering loses its precision, the rear of the vehicle looks loose, and the braking and aquaplaning performance is very poor.

This is how the 225/40 R18 summer tire test is evaluated: The tire with the best value for each criterion receives the full number of points. In terms of steering precision, directness and responsiveness from the central position count, while in terms of driving behavior, the greatest possible neutrality in the limit area.

Conclusion:
The Falken Azenis FK 453 does not leave the fastest in dry conditions, but it does make a sporty, precise impression. Ultimately, however, the tire gives in to understeer. When decelerating from 100 km / h, almost two meters are missing on the best. If the track is wet, the residue grows much further. When it comes to aquaplaning, the Falken doesn't do very well either. Basically there is a lack of grip, but there are jagged, pronounced load change reactions.

When it comes to steering precision, what counts is directness and responsiveness from the central position, and when it comes to driving, the greatest possible neutrality at the limit.
